ACID-CARBOY SUPPORT.

SPECIFICATION forming part of Letters Patent No. 280,860, dated JulyV 1o, 188e.

` `application filed March 523, 1883. (No model.) l

the same, reference being had to the accompal nying drawings, and, to 'letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to means for temporarily providing acid-carboys with a support which enables them -to be readily and easily emptied of their contents; and it consists in the peculiar construction and combination of the supporting and clamping devices hereinafter particularly set forth. Each clamp is so constructed that the position of its tenon may be adjusted to the center of gravity of the carboy-case, in order that the bottom of such case may be made to overbalance its top to any desired extent without requiring measurements to be made, as must be the case to a greater or less extent if the position of the trunnion upon its support is an arbitrary one.

The drawings accompanying this specification represent, in Figure 1, a perspective elevation, and in Fig. 2 a side view, of a carboysupport containing my invention applied to a portion of a earboy in section. Fig. 3 is a front view of the bearing-plate hereinafter de- Fig. 4: is an edge view of one of the standards of the frame, and Fig. 5 an isometric view of an improved method of attaching the two standards together.

In said drawings, A represents the wooden case of an acid-carboy, B being the top thereof. C represents the support for my adjustable device, consisting of upright twin standto a plank or be united by a crossbar or oth- 'pling of the latter.

erwise/coiiiieted. l prefer the construction VShown in Fig. 4 of the drawings,'in which each standard D is formed with three horizontal feet, G. G G, arranged triangularly, or approxi mately so, to provide aftrm bearing upon the iloor. The upper part of the standard D overhangs the lower part in a direction toward the carboy-case, in order to carry the center of gravity of such standard inside of a vertical line drawn through its lower part to prevent liability of said standard to cant out- Ward. at the top. An effective and simple mode of connecting the standards D D is shown in Fig. 5 of the accompanying drawings, which consists in providing each standard near its base with a rigid inwardly-extending abut- Vment or enlargement in which a horizontal groove is formed, and inserting into said grooves the ends of a horizontal bar, H, which is afterward bolted or otherwise secured to said abutment. If the standards be made Sufeiently broad, the inwardly-extending abutments will not be needed.

Each clamp is composed as follows: c represent's a cylindrical trunnion adapted to fit the bearing in thev top of each standard, this trunnion being cast upon the outside of and at right angles to a head or block, b, to bear upon the side of the caseA, this head or block b having lateral arms c c to provide an extendedA bearing-Surface upon the side of the case, and prevent twisting and bending of the 'rods forming part of the clamp. To each end of the head b, I secure one end of a rod, c, and l out a .screw-thread upon the opposite or outer end of each of such rods c c to receive ahandnut, d. Moreover, I pass the outer portion of each rod c loosely through a boss, e, cast upon a bearing-plate, f, which bears upon thelside ofthe case A, near the edge of the latter, this plate .f having a longitudinal groove, g, to receive the wire c and prevent bending' or crip- Each plate f is formed with a lateral toothed jaw, h, to take into the side of the case next adjacent to the plate, the two jaws thus serving tosecure the clamp tightly to such case whenthe nuts d d are IOO case stands upon the floor, the trunnion being van upright position when left alone.

situated near a point slightly above the center of the case, as can be readily determined by the eye, in order that the bottom, of the case may overbalance the top and the carboy remain in After the two clamps have been secured to opposite sides of the case A, as explained, such caseis to be lifted from the floor and the trunnionsa a deposited 4in the bearings E of the standards D D, thus suspending` the case above the floor sufficiently far to enable it to be tipped to the extent necessary to expel its contents, and it will be seen that the construction of my support enables the carboy to be turned completely bottom upward, thereby allowing its entire contents to `run out. Should it be found, after the clamps have been applied to the case, that the trunnions are not in the most favorable position, they may be adjusted by means of the nutsl d d without removing the clamps.

It is desirable that the carboy shall not be greatly overbalanced, but only sufficiently so to permit it to resume an upright position when left alone, and also that the trunnions shall be as nearly opposite each other as possible. If the positions of the trunnions are arbitrary, they 'cannot be changed without considerable labor; hence the value of my improvement in this respect, which enables the position of the trunnions to be changed with ease and celerity without disturbing the positions of the clamps bodily.

1. A device for supporting acid-carboys, consisting of a pair of clamps, each of which con tains jaws to grasp opposite edges of the. carboy-case, and carries a trunnion to rest in bearings in a suitable standard, the device containing also provision for enabling the trunnions to `be changed in position without disturbing Vthe clamp bodily, substantially as and for the purposes set forth.

2. The clamping device herein explained,

consisting of the head b, having trunnions a, the rods c c, the grooved plates f f, with their jaws h, and the nuts d d, coniining such jaws to the case, substantially as stated.

3. In a carboy-support, the standards D D, each of which is constructed with a rigid in- Wardly-extending horizontal piece having a horizontal groove, in combination with a transverse bar, H, which is set into said grooves, substantially as setforth. y

4. A pair of standards provided with inwardlyextending horizontally-grooved pieces near their bases, and having their tops bent inwardly, in combination with a carboy journaled in said bent tops, and a transverse bar fastened in the grooves of said inwardly-extending pieces, substantially as set forth.

5. In combination with an yacid-carboy and case, removable clamps carrying trunnions and adapted to grasp said case, and having provision for enabling the positions of the trunnions to be changed with respect to each4 other and the case without removal from the case, substantially as herein described.

6. The construction of each plate f as having its body grooved longitudinally to receive 7o and steady the rod c, and having the right-angular jaw h to grasp the side of the carboycase, substantially as set forth.

7. The combination, with the grooved plate j', having jaw h,.of the block b, having trun- 75 nions a and right-angular arms o', the rod c, and nuts d, operating on the screw-threaded ends thereof, substantially as set forth.

.8. The combination of the head b, with its trunnion, the screw-rods c c, nuts ld d, and 8o jawed plates ff, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
